GEORGE R. BAKER, OF BROOKLYN, NEW YORK.

MACHINE FOR KNEADING DOUGH.

Specification forming part of Letters Patent No. 50,322, dated October l0, 1865.

.To all whom 'it may concern:

Beit known that I, GEORGE R. BAKER, ot Brooklyn, inthe county of Kings,in the State of New York, have invented a new and useful machine for kneading dough and I do hereby declare thatthe following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, ina-king a part of this specification.

The essential features of my invention consist in an inclosed chamber to contain `the dough, in which a wheel is rotated upon an eccentric but yielding and variable axis of rotation, by the action of which wheel upon the dough thelatteris subjected to a rolling pressure, rapidly repeated, producing an effect upon it similar to that produced by ordinary handkneading, but in much less time and with much less labor.

To enable others to make and use my'invention, I will proceed to describe its construction and operation. Y

In the accompanying` drawings, Figure l is an elevation ot' my machinein perspective, with the upper section ofthe box or chamber removed. Fig. 2 is a cross-section drawn through the line w 9c of Fig. 3. Fig. 3 is a longitudinal vertical section through line x y, Fig. 2. Figs. 4 and 5 are the two parts or sections of the wheel, detached from each other, drawn on an enlarged scale.

Each part of the machine is indicated by the same letter in all the ligures.

A is the lower section ot' the box or vessel containing` the chamber l'or the dough, and A is the upper section of the same.

B is the lower portion ot' the chamber or cavity for the dough, and B is the upper portion of the same.

O is the eccentrically-revolving wheel. O is the inner face of one section ot' said wheel, and C2 the inner face of the other section.

The two sections ofthe box A and Ai are detachable from each other, and may be secured together' by dowel-pinsand hasps,orany other suitable means. The interior of the lower part ofthe box or vessel is a concavity, B, semicircular in the plane of its greatest diameter, and semi-elliptical, or nearly so, in the plane of its greatest transverse diameter. The interior ofthe upper part, B, is formed by merely extending the section shown of the lower by a vertical wall to the top of the box, where it is closed by a sliding cover, D. Within the concavity or chamber so formed a wheel, O, of less diameter and thickness than the chamber, revolves upon an eccentric axis produced by passing through it, outside ot' its center, a compound shaft, a, to which motion is given by a crank, b, outside of the box. The shaft a has an mama/,projecting from itat right angles in the interior ot' the wheel C, which at its outer end terminates in a cross-pivot, c, itting into suitable holes in the two sections of the wheel, (one of which is shown at c/in Fig. 5.) Said arm a has room to play back and forth in a V-shaped recess, d, cut in the inner face ot` the section O of the wheel, and

the main shaft d has a corresponding playin the slot c, passing clear through both sections ofthe wheel.

A rubber sprng,f, (but which may be of tnetah) is fitted into a suitable recess in the inner face ot' the section C ofthe wheel, which 'will keep the shaft a and its projecting arm a in the position shown in the drawings, except when the dough, from its stiffness, oii'ers considerable resistance to the rotation ofthe wheel; but when such resistance occurs the spring will yield, allowing the shaft to change its position in the slot c, varying the eccentricity ofthe axis ot' rotation and shortening the radius of motion ofthe wheel, and thus permitting the dough to pass under.

rlhe two sections of the wheel are fastened together by one or more rivets or bolts, as shown at g.

A suitable quantity of dough is pnt into the kneading-chamber B B, the two sections ot' the box rmly fastened together, and the chamberclosed by the lid D. The operation of lineading is then performed by simply turning the crank.

The box may be provided with suitablemeans for attaching it to a table, if desired.

that I claim as my invention, and desire to secure by Letters Patent, is

l. The machine for kueading dough, constructed and operating substantially as herein described.

2. The combination of the shaft a, with its pivoted arm a', the slot c, and spring j', arranged and operating substantially as and for the purpose herein described.
